In bass lures, size matters. When the water is cold and the bite slow, it usually pays to downsize your presentation, which is why bass pros rely on finesse baits like shaky-head worms during tough early spring, late fall and winter tournaments.
This stands to reason, since bass, being cold-blooded, have a sluggish metabolism and thus require less food intake in cold weather. But in summer, warm water elevates the metabolism of the bass so it needs a constant supply of groceries to keep its body fueled. That’s when the biggest lures in your tackle box can trigger savage strikes.
